Just got the 555 BE on Sunday, unlocked it on Sunday and its be running fine. I really haven't had time to very much overclocking. But I did up the multiplier from 16 to 17.5 hit 3500 with out any problems. Ran prima95 for two hours with out a problems. I have a Corsair H50 cooler and my CPU didn't
even get over 32C. with load. The only question I might have is about ACC.
and what the % has to do with the unlocking of the cores. What effects it will have. Right now BIOS set tham all to 2%.
